| 中文摘要: |
| 研究不同负荷和速度下炭黑和白炭黑填充硫化胶的湿摩擦因数，并对其摩损表面进行了扫描电子显微镜和透射电镜表征。结果表明：炭黑填充硫化胶的湿摩擦因数随着速度的增大呈线性下降，随着负荷的增大略有降低，而白炭黑填充硫化胶的湿摩擦因数随着速度的增大呈非线性下降，随着负荷的增大先迅速下降后缓慢降低；白炭黑填充硫化胶摩擦面橡胶膜较薄，裸露白炭黑粒子，过渡区摩擦力较大，不能忽略；炭黑填充硫化胶表面的橡胶膜厚度较大，表面炭黑粒子被橡胶大分子覆盖，过渡区摩擦力小，可以忽略。 |
| 英文摘要: |
| The wet friction coefficients of carbon black and silica filled vulcanizate under different loads and speeds was studied，and the worn surfaces were characterized by scanning electron microscopy and transmission electron microscopy.The results showed that the wet friction coefficient of carbon black filled vulcanizate decreased linearly with the increase of speed，and slightly decreased with the increase of load，while the wet friction coefficient of silica filled vulcanizate decreased nonlinearly with the increase of speed，and decreased rapidly at first and then slowly decreased with the increase of load.The rubber film on the friction surface of silica filled vulcanizate was thin，and the silica particles were exposed，the friction force in the transition zone was relatively large and could not be ignored.The thickness of the rubber film on the surface of carbon black filled vulcanizate was large，the surface carbon black particles were covered by the rubber macromolecules，and the friction force in the transition zone was small and could be ignored. |
